RADIATOR CURTAIN Filed June 28, 1939 1 lnvenior A ttomeys Patented Apr. 23, 1940 UNITED STATES PATENT OFFICIE 1 Claim.

This invention relates to a curtain for radiators, the general object of the invention being to provide a curtain which can be raised and lowered so as to regulate the amount of air passing 6 through the radiator, the invention being mainly designed for use on a truck.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be here- 10 inafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing where- 15 in like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a perspective view showing the front portion of a truck with the invention thereon and the curtain in raised position.

20 Figure 2 is a section on the line 2--2 of Figure 1.

Figure 3 is one of the bars extending across the curtain.

In this drawing, the numeral l indicates a 2 pair of brackets attached to the front of a truck under the radiator grill and the numeral 2 indicates a pair of upper brackets connected with the upper portion of the radiator assembly. An arched cross bar 3 extends across the top of the 30 radiator structure and has straight end portions provided with slots 4 which rest upon the brackets 2. A pair of vertically arranged rods 5 have their lower ends supported by the brackets I and their upper ends pass through the brackets 2 into the 35 slots 4 of the cross member 3, said upper ends being threaded to receive the nuts 6. Thus the parts are adjustable to make them conform with different types of radiators and different curvatures .of such radiators. The brackets 2 can be 40 connected with the radiator grill by toggle bolts. The curtain is formed of canvas or the like and is provided with a plurality of transversely extending pockets or casings 8 each of which receives rings Ill. The arched part of the cross member 3 carries a pulley l2 over which a chain l3 passes, the front end of the chain being forked with the parts thereof attached to the top of the curtain and said chain passes rearwardly through a 5 slotted bracket l4 attached to the vehicle body adjacent the drivers side thereof so that the driver can manipulate the chain to raise and lower the curtain, it being understood that the curtain will drop by gravity, due to the weight 10 of the rods 9 when the chain is slackened.

Thus it will be seen that I have provided a simple but effective arrangement for controlling the flow of air through the radiator by simply raising and lowering the curtain which extends across the front of the radiator.

The arch bar 3 may be formed of two pieces bolted together at the top so that the bar can be adjusted to fit different curvatures of radiators.

It is thought from the. foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.

Having described the invention, what is claimed as new is:

A curtain of the class described comprising upper and lower brackets, vertically arranged rods having their ends connected with the brackets, a fabric curtain, vertically spaced and transversely extending casings on the front of the curtain, transverse rods passing through the casings, rings connected with the casings and engaging the vertically arranged rods, vertically arranged reinforcing strips connected with the front of the curtain where the rings connect with the casings, an arched cross member having its ends connected with the upper brackets, a pulley carried by the arched part thereof and a flexible member passing over the pulley and connected with the top of the curtain, whereby said curtain may be raised and lowered.
